Answer 3

Problem Analysis

A ant is at the bottom of a well that is 30 meters deep. During the day, it climbs up 18 meters, but at night it slides down 12 meters. We need to determine how many days it will take for the ant to climb out of the well.

Solution

To find the number of days it will take for the ant to climb out of the well, we need to calculate the net distance the ant covers each day.

During the day, the ant climbs up 18 meters, and at night it slides down 12 meters. Therefore, the net distance the ant covers each day is the difference between the distance climbed during the day and the distance slid down at night.

Net distance covered each day = Distance climbed during the day - Distance slid down at night

Let's calculate the net distance covered each day:

Net distance covered each day = 18 meters - 12 meters = 6 meters

Since the net distance covered each day is 6 meters, the ant will climb out of the well in 5 days.

Answer

It will take the ant 5 days to climb out of the well.
